Fixes F7 from mobile-chat audit #2908.

MobileChat cleared draft and pendingFiles before awaiting sendMessage, so a genuine send error left the composer empty with no way to retry. This PR snapshots the composer state before clearing and restores it when sendError surfaces.

Validation

• npm run build in canvas/ passes.
• npx vitest run src/components/mobile/__tests__/MobileChat.test.tsx passes (41/41), including a new regression test that verifies the textarea is repopulated after the "agent may be unreachable" banner appears.

Relates-to: #2908

MobileChat cleared draft and pending files before awaiting sendMessage, so

the composer state before clearing and restore it when sendError surfaces.
Adds a regression test verifying the textarea is repopulated after the
"agent may be unreachable" banner appears.

APPROVED after independent 5-axis review.

Correctness: mobile now snapshots draft text and attachments before clearing the composer, then restores them only when a genuine sendError surfaces. The snapshot is cleared after restore and overwritten on each send, so retry behavior is scoped to the failed send. Robustness: test covers the rejected-send path. Security/performance: no meaningful risk; files are already local pending attachments. Readability: minimal hook-level state with clear intent.

APPROVED. 5-axis review on head 8991b5d0.

Correctness: MobileChat snapshots the composer state before clearing it and restores draft/files when useChatSend surfaces a genuine sendError, so the user can retry after the unreachable/send-failure path. The snapshot is cleared after restore, avoiding repeated restores on unrelated later error state changes.

Robustness/security/performance: local React state only; no new network or auth behavior. File references are preserved in memory for retry and cleared on success/normal reachable flows as before.

Readability/tests: the regression test exercises the visible error banner and verifies the textarea is repopulated. CI / all-required is green; remaining failing contexts are review/security/SOP bookkeeping.
